CompTIA Linux+ XK0-006 (V8) Practice Question

During a routine maintenance window, an administrator runs sudo apt update on an Ubuntu 22.04 LTS server and receives the following output:

Err: http://archive.ubuntu.com/ubuntu focal InRelease
  404  Not Found [IP: 185.125.190.39 80]
Reading package lists... Done
E: The repository 'http://archive.ubuntu.com/ubuntu focal InRelease' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

A quick check of /etc/lsb-release returns:

DISTRIB_DESCRIPTION="Ubuntu 22.04.4 LTS"
DISTRIB_CODENAME=jammy

Which of the following actions will MOST likely restore normal update functionality while maintaining security best practices?

  • Edit the APT source files to replace every instance of focal with jammy, then run sudo apt update again.

  • Run sudo apt clean and retry the command to rebuild the local APT cache.

  • Add the repository's public key with apt-key adv --recv-keys to re-enable package verification.

  • Change the protocol from http to https for each entry in /etc/apt/sources.list.
